Intermediate shaft wear ?? Possible fixes ? #1616186 05/05/14 02:56 AM 05/05/14 02:56 AM

I pulled the intermediate shaft only to find it scuffed and galled like I did on the last one when I swapped to my last cam. That was about a year ago. I installed a new bronze bushing and a used intermediate shaft I had from another motor. Removing the old bronze bushing was a nightmare !!! Basically had to chisel it out. ... I'm bummed to see the new shaft wearing out the same way. The bushing looks to be in good shape. It only looks like the shaft is wearing like this. Any ideas on the probable cause of this? ? Any suggested fixes ??? Any help would be great... thanks , Dave 8134474-2014-05-0420.54.10.jpg (206 downloads) Last edited by Torquemonster440; 05/05/14 03:00 AM. 1966 Satellie.. 12.55 @107.75. 906 heads. 3780 lbs.

You put a locking 1/2"caller from Grainger or others on the dist shaft to limit the up/down movement to under .010 but the side limit is in the bushing.

Instead of a Mopar bushing, use a Pioneer one which you can just press in with no additional burnishing required. Check your dizzy for end play - how much the shaft moves up and down. Now install the dizzy and see if you still have that same movement. If not, then that's the issue ... the dizzy is putting pressure on the bushing. If the endplay is still there then the smart thing to do is pull the intake and valley cover and see how much play you have between the two - more than about .010" is not desirable and you'll want to put a collar at the base of the dist shaft to limit the play. And use red Loctite on the collar screw - you don't need that sucker falling out!!

When the dizzy is locked in I have the same amount as when it's out of the car, so I don't think it's preloading the shaft from the top. I have no side to side movement, but I checked the up and down with a feeler gage and got about .022 of movement. Could this be my problem? ? Also, when I installed the new bushing I just drove it home with the old shaft and a brass drift.I believe it's the pioneer style, I didn't burnish it. 8137629-2014-05-0420.55.25.jpg (150 downloads) Last edited by Torquemonster440; 05/07/14 10:41 PM. 1966 Satellie.. 12.55 @107.75. 906 heads. 3780 lbs.

I know big block chevy require a puller. They slide on.... it looks like you have a lack of oil up there on the shaft/bushing... thats not much wear but you should prelube the shaft/bushing on install.. the collar helps to stabilize the timing.. as the intermediate shaft lifts and drops it turns so that does the same thing to the timing... put the collar on just snug so it a minor bit of force it can slide.. put the dist in and clamp it down... remove the dist and move the collar up a few thousandths then tighten and reinstall the dist and set timing

Mine just slides off the crank snout easily. I know big block chevy require a puller. The gear will seat against the crank on the back side to keep things in line but the crank should be a very close fit in the gear so I have to ask were they the same temperature and is it on there now where they are the same temp?and does it move still?When you put on the damper/ballancer it will hold the gear seated also I believe.

Yes, the gear fits snug on the snout, just wanted to make sure nothing was "a miss". What do you think could be impeding oil flow?? A clogged oil galley? ?? The pump makes good pressure 70 cold @ fire up and between 50- 55 @ warm idle. I've been running the Valveoline VR 50wt racing oil for the extra zinc?? Could this be a cause??

I'd heard that a 50wt would help quiet them down. Now that I'm swapping for the ol'skool solid stick I think I'll switch back to the 10-30 with the zddp addative. 1966 Satellie.. 12.55 @107.75. 906 heads. 3780 lbs.
